Hello everyone. I am having trouble with my 1995 Seadoo. Last time I used it about 3 weeks ago it seemed to run fine. When I got back to the house with it I flushed the motor using salt-off, and it ran fine. I just went to winterize it and I could not start it. It seemed to have no spark, while I had the spark plugs out I checked the compression. Both cylinders were reading 60psi. I was thinking it was odd that they were both so low, so I bought a new compression tester and got the same reading. I checked the compression when I bought it and the reading was 130psi in both cylinders(3yrs. ago). I changed the coil and now have spark but it will not start. Is 60 psi too low to even fire up and is there any thing besides the piston, rings, and head gaskets that would cause such low compression. I use very little oil each season but read on the forum using the Seadoo oil and pump should use little oil. I probably use 20 gallon of gas a year and about 1/2 quart of oil. I am thinking of pulling off the head to see the cylinders. I am a machinist so boring and honing the cylinders are no big deal for me. If anyone has any thoughts or input I would greatly appreciate it. Thank you in advance.
